Title: Improvements in or relating to variable resistance devices especially for use in radio apparatus
Filed: 1925-09-28
Abstract: 261,148. Curtis, A. H., Holdway, G., and Igranic Electric Co., Ltd. Sept. 28, 1925. Variable resistances. - In a rheostat of the type comprising a helically wound wire mounted on a rotatable drum the resistance element is electrically connected to the spindle of the drum by a radial arm which also holds the resistance element in place. The resistance wire 1 is wound on a strip of fibre &c. 2 which is wrapped round a drum 3 of insulating material. A metal plate 9 passes over the spindle 7 of the drum 3 and is furnished with two lugs 9a which pass through holes in the strip 2 and are turned over to hold it in place. One end 8 of the resistance Wire is attached to the arm 9. The spindle 7 is mounted in a sleve 12 having a squared part 12a which fits between the flanges of a channel plate 13 which also carries a rod 17 on which is a terminal 5. An insulating sleeve 17<a> surrounds the rod 17 and supports a spring arm 4 making contact with the resistance wire. The drum 3 is formed with a flange 3<b> against which the resistance element abuts and this flange is cut away in places and the drum correspondingly recessed that the air may have access to the resistance wire. The spindle 7 carries the usual graduated knob 11 and a hog-backed spring 21 bears against the knob and the panel, into which points 21<b>, 21<c> on the spring dig. The end of the spring is turned over to form a pointer 21<a>.

Title: Method of making composite photographs
IPC: G03B15/08
Filed: 1930-08-14
Abstract: 365,134. composite photographs ; optical systems. POMEROY, R. J., 1626, North Crescent Heights, Los Angeles, and PARAMOUNT PUBLIX CORPORATION, Paramount Building, Times Square, New York, both in U.S.A. Aug. 14, 1930, No. 24404. [Classes 97 (i) and 98 (ii).] Relates to the production of composite photographs embodying two component images by illuminating one component with light of a selected colour before a ground illuminated with light of a complementary colour and forming on a sensitive film two images, one exclusively in light of the selected colour and consisting of the first component and the other exclusively in light of the complementary colour and consisting of light which comes from the ground around the first component and passes through a transparent film bearing an image of the second component ; and consists in casting the two images on opposite sides of the sensitive film. As shown, an object 12 is illuminated by blue light 13 in front of a plain red background 10 illuminated by red light 11. An image of the combination formed by a lens 12 is split by a reflecting prism system 15, 16, reversing prism 25 and glass equalizing block 26 into two parts which are projected on to opposite sides of a sensitive kinematograph film 17 which may be a double-coated stock. A black and white background kinematograph diapositive 18 is placed in contact with the film 17 and blue and red filters are interposed respectively at 19, 20. The blue filter transmits an image of the object 12 to one side of the film 17 while the other side receives an image of the background printed through the background positive 18. The relative densities of the two images may be varied by regulating the densities of the filters 19, 20 or by moving the prism system relatively to the lens 14. The object 12 may be replated by a photograph or painting; or by a blue-toned kinematograph picture film 30 of a moving object photographed in front of a non-actinic ground.

Abstract: 1447179 Shearing KOBE STEEL Ltd 3 June 1974 [5 June 1973 11 Aug 1973 22 Dec 1973 (2) 22 March 1974] 24539/74 Heading B3W Apparatus for shearing the transverse members 3<SP>1</SP> of wire mesh 3 comprises shearing edges 1, 2, a groove 10, extending downstream from and parallel to the cutting line, through which the mesh passes and a drive pawl device 11 located adjacent the open side of the groove and adapted to engage a longitudinal member 3<SP>11</SP> and drive the transverse members forward to advance the mesh in a direction parallel to the groove so that successive transverse members are sheared by the edges 1, 2. The drive pawl device comprises pawls 13 pivoted to a driven chain 12 and having follower rolls 17 engaging cam 14 to restrict their pivoting in one direction so that they drive the mesh. At the beginning of a shearing operation the device 11 is adjusted relative to the cutting line by means of a screw 19 so that a longitudinal member 3<SP>11</SP> a required distance from the cutting line engages in a central slot 15 in the pawls. The chain motor is then actuated to bring the front face of at least one pawl against a transverse member 3<SP>1</SP>. Should a member 3<SP>1</SP> engage the rear face of a pawl the pawl will pivot out of the way. The member 3<SP>11</SP> is kept in the slots 15 by a cover 20. The support 8 of a fixed upper blade 1 is mounted on a member 9 fixed to the main frame 4. The movable blade 2 is mounted in the frame 4 for orbital movement by eccentrics 5, 6 so that it moves generally in the feed direction during shearing. The groove 10 is formed by the lower surface of the support 8, the upper surface of the frame 4 and a side face of the member 9. As the members 3<SP>1</SP> of the mesh is cut, the stock to the right of the blades rides up an inclined upper surface of the member 9, Fig. 1.

Title: Improvements relating to the manufacture of beer
Inventor: FREITAG ROBERT BERNHARD BRUNO

Abstract: Kaffir beer is made by adding to warm water a cereal material admixed with one or more organic acids and without preliminary bacteriological souring, cooking, cooling, and then adding a malted diastatic material to the formed porridge to liquefy and convert starch to sugar whereupon yeast is added and fermentation allowed to proceed for a suitable period.  Specified cereals are mealic meal and kaffir corn meal whilst the diastatic material can be a malt of barkey, maize, rapoko, nyouti or wheat.  If desired, the later stages of brewing can be carried out by the consumer (i.e. the addition of water and yeast and allowing fermentation) by preparing a mixture comprising the product of cooking and drying a cereal material having a souring medium of one or more organic acids and having admixed therewith, either before or after drying, a diastatic malted material.

A spinneret for making variegated filaments comprises a spinning head 11 fitted to a cylindrical chamber 12, cap 13 and spinneret plate 16, the chamber also containing a second spinneret 29 comprising a tube 27, manifold 32 and arms 33 each having a plurality of spaced holes 36. A first spinning solution is supplied through a pipe 21 to a plurality of ports 20 in the chamber 12. A second spinning solution which may be of a different colour or composition from the first is supplied through the pipe 27a, 27 to the manifold 32 and is extruded through the holes 36 to form a plurality of streams of the second spinning solution within the bulk of the first spinning solution in the chamber 12. With the spinneret 29 stationary, the first spinning solution flows through one side of one of the holes in the spinneret 16, and the second through the other side of the same hole, so that a " side-by-side " type of composite filament is obtained, the junction between the two spinning solutions being longitudinal. By oscillation of the tube 27 by means of the lever 47 and mechanism 48, the streams leaving the holes 36 are made to define sinusoidal paths. Oscillation of the tube 27 at a fast rate or through a large amplitude enables filaments to be obtained having alternate longitudinal segments of the two spinning solutions, the junction between any two segments being substantially transverse. Oscillation of the tube 27 at a slow rate or through a small amplitude enables variegated filaments to be obtained in which the junction between the two solutions is intermediate between transverse and longitudinal.
